Zoe
walked out of Everglades K-8 Center and was assisted across the street
by a campus security guard, CBS reports. She reportedly told the guard
that she was not feeling well.

After Zoe got home, her aunt went to the school and found school
personnel driving around the neighborhood looking for Zoe, but the
school had not contacted the family to tell them she was missing,
according to Local 10.

For
now, the Maglios are keeping Zoe enrolled at the school, but demanding
that an assistant be with Zoe at all times when she is on campus. They
are considering legal action, CBS reports.

The school district has apologized to the family and fired the security guard who let Zoe leave.

"Miami-Dade
County Public Schools has strict guidelines in place to ensure student
safety," the district said in a statement. "Today, there was a breach of protocol by a school employee who
did not follow those guidelines. The employee has been terminated and
will not be rehired."

Zoe was diagnosed with autism last fall. A 2012 study by Autism Speaks found that nearly half of children with autism wander -- defined in the study as leaving a supervised, safe space and thus "exposing him or herself to potential danger."

When
children with autism wander, they may not recognize potential dangers.
"In some cases they can’t communicate that they’re lost or in trouble,"
said Lisa Goring, executive vice president of programs and services at Autism
Speaks.
